Filtering
Performance
When used in conjunction with an efficient dust
collection system, the Model T33150 and T33151
remove most fine wood particles up to 0.3 microns
from the air. The air filters are capable of recircu-
lating the air in a room measuring 25' x 25' x 8'
approximately the following number of times per
hour:
— T33150: 7.5 times at 620 CFM.
—
T33151: 16.8 times at 1400 CFM.
We recommend that the volume of air in your
room be recirculated 6–8 times per hour for the
best filtering effect.
Therefore, rooms with a larger volume may require
two or more air filters to achieve proper filtering.

2. Calculate how many times per hour the room
volume is recirculated through the air filter by
dividing 60 minutes by the circulating time from
Step 1. This will give you how many times
an hour the air in the room is recirculated
through the air filter.
To calculate the recirculating rate for your
shop space:
1. Calculate the volume of air in your shop by
multiplying the length x width x height of the
room (see the example below). Then, divide
the volume by the speed (CFM) you have
chosen to operate the air filter. This will give
you how many minutes it takes to recirculate
the air in the room.
Example: The room measures 25' x 25' x 8'
and you are operating the air filter at 1290
CFM (HI).
